[0022] Example 1
[0023] (1) Preparation of rod-shaped cadmium sulfide (CdS NRs): 20.25mmol CdCl 2 ·2.5H 2 O (4.62g) and 60.75mmol CH 4 N 2 S (4.62 g) was added to a 100 mL autoclave containing 60 mL of ethylenediamine and sealed, and the autoclave was transferred to 160° C., and the reaction time was 48 h. .Wash the obtained yellow powder with water and ethanol to remove impurities, and centrifuge to filter and dry the product;
[0024] (2) UIO-66(NH 2 ) Preparation: ZrCl 4 (0.2332g, 1.0mmol) and 2-NH 2 -Terephthalic acid (0.1812g, 1.0mmol) was dissolved in DMF (50mL), then the solution was transferred to a 100ml autoclave, the autoclave was sealed and heated in an oven at 120°C for 24h. The obtained sample was washed several times with anhydrous methanol to ensure that the enclosed DMF molecules were removed, and then dried under vacuum (100°C, 12 hours);
[0025] (3) UIO-66(NH 2 ) Preparation of doped rod-shaped cadmium sulfide (CdS NRs) composite photocatalyst: 1.812g of rod-sh...
